It is resistant to high temperature and can withstand large temperature and pressure differences.
Although the wall of the corrugated tube is very thin (0.6-1.2mm), the pressure bearing capacity is greatly improved due to its special free forming process and unique arc shape. The one-way failure pressure of the laboratory wave measuring tube is generally about 20Mpa, and it is safe to control it below 6.4Mpa in actual use.
On the other hand, the corrugated tube heat exchanger is made of stainless steel, which can adapt to higher working temperature and can accommodate up to 450 ° C. The corrugated tube is a flexible component with a certain thermal compensation ability, which is suitable for large operating temperature differences. It has good adaptability and low thermal stress of equipment, which has considerable advantages compared with ordinary pipes.
1.Powerful anti-scaling and descaling function.
Scaling, corrosion and clogging of heat exchangers have always been a difficult problem to solve, especially when the water quality is poor, the water treatment effect is not good, the gas medium contains impurities or chemical reactions are prone to scaling. In some cases, the function of the light heat exchanger decreases, the working conditions deteriorate, the resistance increases, and the energy consumption increases. In other cases, the heat exchanger is clogged and unable to operate, thus increasing the effort to maintain, clean or update the heat exchanger.
The stainless steel corrugated tube is made of high-quality stainless steel material, which has corrosion resistance, and more importantly, the corrugated tube has a special inner and outer corrugation. The turbulent medium continuously scours the inner and outer surfaces of the heat exchange tubes, making it difficult for dust to accumulate on the surfaces. Even if there is dust, the corrugated tube is a flexible member, so after being affected by the temperature difference during the working process, the curvature of each part of the corrugated tube will change continuously, and the deformation caused by these curvature changes is not large. The linear expansion coefficient of the dirt and the metal corrugated tube is very different, and there is a great tension between the dirt and the surface of the broken wall tube, which is enough to remove scale, automatic cleaning and dirt, especially this is the heat exchange of tube and other heat exchangers. incomparable.
2.Uniform stress distribution and strong corrosion resistance.
Because the bellows tube adopts a unique forming process, namely “free forming” or “soft forming”, therefore: the deformation during the forming process is not caused by the forced flow of metal in the mold, but the free flow process or “soft forming” “Characteristics of the process. Because there is no forced deformation, this molding process will not cause stress concentration, the residual stress is small, the stress distribution is uniform, and there are no defects between the crystals, so it has a strong resistance to stress corrosion.
3.Long service life and reasonable price.
Because the bellows tube is made of ultra-thin stainless steel, on the one hand, the service life of the product is prolonged, and on the other hand, the weight of the product is greatly reduced and materials are saved. On the other hand, the operation and maintenance cost is reduced, the floor space is reduced, the cost performance of the product is greatly improved, and the economic benefit is obvious.
